Aluminum Test

Aluminum is a lightweight metal found widely in cookware, food additives, antacids, buffered aspirin, cosmetics, and some vaccines. The body has no biological need for aluminum, and absorption from the gut is usually low. Once absorbed, aluminum binds to proteins and can accumulate in bone and brain tissue. The kidneys are responsible for clearing it through urine.

Higher urine aluminum levels suggest recent or ongoing exposure, especially from medications or occupational sources. Chronically elevated exposure has been associated with bone softening, anemia, and neurologic symptoms, particularly in people with impaired kidney function. In patients with kidney disease, aluminum clearance is reduced, increasing toxicity risk even at modest exposures.

Lower levels generally reflect minimal exposure and effective renal elimination. Urine testing is useful for assessing current exposure but does not fully capture long term tissue accumulation, particularly in bone.
